How Do You Switch the First and Last Digit of a Number in Python?

Here is a comprehensive breakdown concerning How Do You Switch the First and Last Digit of a Number in Python.

To finding first digit of a number is little expensive than last digit. To find first digit of a number we divide the given number by 10 until number is greater than 10. At the end we are left with the first digit.

How do you change a 2 digit number?

This is how to swap two numbers without using a third variable.

1. #include
2. int main()
3. {
4. int a,b;
5. printf(“Enter the numbers you want to swap”);
6. scanf(“%d%d”,&a , &b);
7. a=a+b;
8. b=a-b;

How do I change the first and last digit in C++?

Write C++ program to swap first and last digit of a number

1. #include
2. {
3. int num, last, first, temp, swap, count = 0;
4. //Reading a number from user.
5. cout<<“Enter any number:”;
6. cin>>num;
7. temp = num;
8. last = temp % 10;

How do you swap digits in Python?

Maximum Swap in Python

1. num := cut each digit from the number, and make a list.
2. num1 := sort the num in reverse order.
3. index := 0.
4. while index < length of num. if num1[index] is not same as num[index]
5. join the numbers present in num and make this as integer.
6. return the result.

How do you find the second digit of a number?

You can do it by dividing by ten and then taking the remainder of division by ten: int second = (number / 10) % 10; In general, you could think of integer-dividing by a k -th power of ten as of dropping k least significant digits.

How do you convert to int?

Java int to String Example using Integer. toString()

1. public class IntToStringExample2{
2. public static void main(String args[]){
3. int i=200;
4. String s=Integer.toString(i);
5. System.out.println(i+100);//300 because + is binary plus operator.
6. System.out.println(s+100);//200100 because + is string concatenation operator.
7. }}

How do you swap digits?

Algorithm to swap first and last digit of a number:

1. Ask the user to enter an integer number. Suppose n = 12345, where n is an integer variable.
2. To find the last digit of a number, we use modulo operator %.
3. Find the first digit with the help of mathematical operation.
4. Use below logic to swap first and the last digit.
